Distribution: From the Canaries and N. Africa to Tropical Africa and eastwards to Central Asia and Northern India. Common in desert and semidesert, by roadsides and in gardens from near sea-level to 5000'/1525 m.

Jeffreys 4 is erroneously recorded by Stewart as Euphorbia humifusa Willd., a species of E. Europe and Central Asia. The Waziristan record (material not seen) is thus also suspect., Many Pakistan gatherings that have been determined as Euphorbia thymifolia are either referable to Euphorbia granulate or Euphorbia prostrate. The records for Euphorbia inaequilatera Send. are also almost certainly referable here.
